The distance of the point ( x , y ) from Y axis is

1. |x|
2. y
3. x
4. |y|

Orthocentre of the triangle formed by the lines x + y = 1 and xy = 0 is

One of the equations of lines passing through the point (3, − 2) and inclined at 60º to the line √3 x + y = 1 is

The angle between lines 2x² − 7xy + 3y² = 0 is

Projection (the foot of perpendicular) from ( x , y ) on the x – axis is

The equation y−y1=m(x−x1),m∈R, represents all lines through the point (x1,y1) except the line

If the lines x + 2ay + a = 0, x + 3by + b = 0 and x + 4cy + c = 0 are concurrent, then a, b, c are in
